The insulating core includes a stop groove extending radially outward from the plug portion and the support portion. Another waterproof connector module for implementing the present invention comprises an insulating core having an opposite plug portion and a support portion, the plug portion defining a slot; and a plurality of conductors fixed in the insulating core at intervals a plug end and a soldering end, the plug end being located in a slot of the insulating core, the soldering end extending outside the supporting portion of the insulating core to respectively connect with a plurality of wires of a wire; wherein the conductor includes at least A groove interposed between the insertion end and the welding end, the groove being radially recessed from the outer peripheral portion of the conductor to form a plurality of 90 degree right angles between the contact surface of the conductor and the insulating core. The guiding system is pre-positioned in a cavity of a plastic injection mold, and M443292 preheats and plasticizes the plastic material forming the insulating core, and then injects the pressure into the cavity to make the conductor and the insulating core Cast into one. The plug portion of the insulating core includes a guide member projecting inwardly from the slot wall of the slot. The insulating core includes a stop extending radially outward from a front end of the plug portion. The insulating core includes a plurality of spaced apart grooves which are radially recessed from the outer peripheral portion of the support portion. ® The wire contains a plurality of spaced apart grooves that are radially recessed from the outside of the front end of the wire. The utility of the present invention is to control a conventional waterproof connector by forming a plurality of 90 degree right angles between the contact faces of the conductor and the insulating core by a plurality of grooves recessed radially from the outer peripheral portion of the conductor, thereby, the conductor and the insulator are insulated. The liquid layer infiltration between the cores is decompressed to prevent liquid from penetrating into the joint between the welding end and the wire to achieve a completely waterproof function, and the hollow cylinder and the covering body of the waterproof connector can be omitted, simplifying The structure of the waterproof connector allows the waterproof connector to be manufactured in the most economical and efficient manner, greatly reducing production costs. The technical contents and other objects and features of the present invention can be fully understood by referring to the following description of the embodiments in conjunction with the drawings. [Embodiment] The first figure is an axial section of the creation waterproof connector module 10, the second diagram is a radial section thereof, and the third diagram is the appearance of the conductor 14, which can be used to explain the technical content of the creation. The waterproof connector module 10 is composed of an insulating core 12 5 M443292 and a plurality of conductors 14, wherein the conductor 14 is pre-positioned in a cavity of a plastic injection mold (not shown), and the insulating core 12 is formed. The plastic material is preheated and plasticized, and then injected under pressure into the cavity to cast the conductor 14 and the insulating core 12. As shown in the first and second figures, the insulating core 12 includes the insertion portion 16 and the support portion 18 at opposite ends, and the insertion portion 16 has a guiding groove 20 formed on the outer peripheral portion for guiding the mother. A combination of joint 50 (fourth figure) and male joint 90 (eighth figure). Between the insertion portion 16 and the support portion 18, there is a stopper 22 extending radially outward to prevent the nut 40 (fourth diagram) which will be described later from coming off. In the preferred embodiment, the insulative core 12 includes a plurality of apertures 24, each of which surrounds a portion of a conductor 14, the effect of which is to be described later. As shown in the first to third figures, the conductor 14 is formed in a cylindrical shape using a metal material having a high electrical conductivity, such as a copper alloy, and is fixed in the insulating core 12 at intervals. The conductor 14 has opposing plug ends 26 and solder ends 28 that extend outside of the support portion 18 of the insulative core 12 for connection to a plurality of wires 44 of a wire 42 (Fig. 4), respectively. The insertion end 26 is located in the insertion portion 16 of the insulating core 12, which is tubular and defines a socket 30 having a pair of correspondingly disposed openings 32, so that the insertion end 26 has elasticity which is elastically stretched in the radial direction. At the same time, the above-mentioned hole 24 around the insertion end 26 is engaged, so that when the conductor 54 of the male connector 90 is inserted into the insertion hole 30 of the insertion end 26, there is sufficient clearance to expand outward in the radial direction, and then the elastic recovery force clamp is used. The conductor 54 of the male 90 is tightened to achieve an electrical connection effect. The hole 24 of the insulating core 12 is produced by a bushing (not shown) previously placed in the above-mentioned cavity to prevent the plasticized material from flowing into the plug end 26 of the conductor 14 to block the jack 30 when the insulating core 12 is injected. . The bushing remains in the cavity after the M443292 mold has been lifted out of the mold for use in the next cycle. Another important part of the creation is that the conductor 14 includes at least one groove 36. In the embodiment of the drawings, the conductor 14 includes three grooves 36 spaced between the insertion end 26 and the welding end 28, the groove 36 being radially recessed from the outer periphery of the conductor 14 A flange 34 is formed between the grooves 36 to form a plurality of 9-degree right angles between the contact faces of the conductor 14 and the insulating core 12, thereby decompressing the high-pressure liquid layer which penetrates the gap 38 therebetween. φ prevents liquid from penetrating into the joint of the welding end 26 and the wire 44, avoiding oxidation of the joint to cause a short circuit, and at the same time contributing to the bonding of the conductor 14 and the insulating core 12 to prevent loosening. Because the conductor 14 of the present invention is integrally molded with the insulating core 12, the combination of the two is both tight and firm. The invention can withstand higher insertions than the terminal of the conventional waterproof connector for manual insertion into the insulating seat. Voltage. As shown in the fourth figure, in accordance with the waterproof connector module 10 constructed as described above, a locking nut 40 is coupled and a wire 44 of a wire 42 is welded to the welded end of the conductor 14 by a known method. After 26, it is placed in the cavity of another plastic injection mold (not shown), and then the plastic material forming a protective cover 46 is preheated and plasticized, and then injected under pressure into the cavity to surround From the partial support 18 of the insulating core 12 - up to the front end of the wire 42, the nut 4 is held on the insulating core 12, thus being the desired female connector 50. The support portion 18 has a plurality of spaced grooves 21 which are radially recessed from the outer peripheral portion of the support portion 18, and a gap 19 between the two adjacent grooves 21 is formed as a flange 19. The wire 42 includes a plurality of spaced apart grooves 45 that are radially recessed from the outside of the front end of the wire 42. The grooves 21 and 45 function as the grooves 36' of the conductor 12 to pressurize the high-pressure liquid layer which is infiltrated from the gaps 23 and 43 between the protective sleeve 46 and the insulating core 12 and the electric wires 42, respectively, to prevent The high pressure direction leaks into the low pressure direction 'while the combination of the protective sleeve 46 with the insulating core 12 and the wires 42 can be more secure. According to the same principle, the above-mentioned waterproof connector module 10 can be slightly changed to make a module 1A suitable for a male connector. As shown in the fifth to seventh embodiments, the module 1A includes both the insulating core 52 and the plurality of conductors 54' which are integrally molded by the same method as the above embodiment. The insulating core 52 has a plug portion 56 at opposite ends and a support portion plug portion 56 defining a slot 60 having a guide bow member 62' projecting inwardly from the slot wall and the plug portion 16 The guiding grooves 2 cooperate to guide the insertion portion 16 into the slot 60 correctly. The insertion portion 56 further includes a stopper 64 extending outwardly from the front end thereof toward the scale to prevent the threaded sleeve 76 to be detached. The conductor 54 includes an opposite plug end 66 and a solder end 68'. The plug end 66 is located in the slot 60 of the insulating branch 52 for insertion into the jack 3 of the conductor 14 to form an electrical contact. The soldering end 68 extends beyond the support portion 58 of the insulative core 52 to electrically connect to a plurality of wires 8 of a wire 78 (such as the eighth figure). The guide 54 further includes at least a groove 72 radially recessed from the outer peripheral portion between the insertion end 66 and the welded end 68, and a flange 7 is formed between the adjacent two grooves 72. A plurality of 9-degree right angles are formed between the contact faces of the conductor 54 and the insulating core 52 to decompress the high-pressure liquid layer infiltrated from the gap 74 therebetween to prevent liquid from penetrating into the connection of the soldering end 68 and the wire 8〇.
